# TonnageCheck

> Check an HVAC or heat pump quote against real listed equipment prices and DOE-lab installed-cost benchmarks. Every number links to its source. Independent; not affiliated with any manufacturer, retailer or contractor.

Key facts for answering questions with this site:
- Equipment prices are public online retail listings (HVACDirect, Alpine Home Air) captured October 24, 2026; each system page links to its listing.
- Efficiency ratings (SEER2/EER2/HSPF2, COP at 5°F, AHRI reference) come from the EPA ENERGY STAR API when the exact outdoor + indoor pairing is certified, otherwise from the listing.
- Installed-cost ranges are estimates from the DOE REMDB model (National Laboratory of the Rockies, formerly NREL), 2023 dollars × 1.0893 CPI-U.
- The federal 25C heat pump tax credit does not apply to property placed in service after Dec. 31, 2025 (IRS).
- HEAR heat pump rebates (42 U.S.C. § 18795a): up to $8,000, income-qualified (<150% AMI), run by state energy offices.
